Yesterday I received an email from one of my customers, he told me that he wanted wireless PIR detector with solar power.
I told him wireless PIR and solar power can't be exist at the same detector. You guys know why?
OK, let me tell you!
Wireless PIR detectos can't be solar power, because wireless PIR detectors at outdoor area is not stable, because the outdoor temperature difference, and sunlight will make wireless detectors false alarm. That's the reason why wireless PIR detectors can't be wireless and solar power at the same time.
